Flowmaster Original 40 Series Mufflers Reviews

My current project of restoring a 1980 Chevy Van has been an enjoyable experience. Now with all of the mechanical restoration complete. I wanted to give the van a real feel of the type of exhaust system a small block chevy should have. The custom ordered exhaust along with the classic "Flowmaster 40" Mufflers completed this task. Wow what an improvement in overall output performance as well as that classic "Street Rod" sound.
